And you have covered all the basics? Set up forums correctly in the buddypress settings, Permlinks are working correctly, When you say go into ‘It’ what do you mean by ‘it’, the top level directory for forum posts.

Have you tested basic functionality with the default buddypress theme enabled to see if this is a theme related issue?

You will need to provide slightly more detailed info , version numbers for WP/BP are also important.
